The duo finished at 11th place in the short program

North Korea's figure skaters have made their debut at the Winter Olympics, showing off an "electric" routine that earned them a spot in the qualifying round.

Ryom Tae-ok and Kim Ju-sik were greeted by cheers as they performed their routine, set to an instrumental cover of The Beatles' "A Day in the Life".

The performance on Wednesday saw the duo reach their personal best score.

They are the only North Korean athletes to qualify for the 2018 Games on merit.

Opening their routine with a triple twist lift, the duo were cheered on by a swarm of North Korean cheerleaders who wore red and white tracksuits and waved North Korean flags.

The participation of North Korean athletes and cultural troupes in the Olympics has not been without controversy, as some critics question the North's commitment to reconciliation and others warn it will change nothing on the nuclear front.

North Korea's cheerleaders were out in full force

Ms Ryom, 19, and Mr Kim, 25, finished with 69.40 points, their personal best score for the short program - landing them a spot in the 11th place.

The interaction is one of several visible moments of friendship between the North and South Korean athletes, who this year marched under a single "unification flag" at the Olympics opening ceremony.

Pyongyang has sent some 22 athletes and more than 400 delegates, including a team of cheerleaders and an orchestra, to this year's Winter Games.

The Games are currently taking place in the wake of long-running tension over North Korea's nuclear programme.

Kim Jong-un surprised many in his televised new-year speech, when - amid threats against the US - he first expressed support for the Winter Olympics and a wish to "melt the frozen North-South relations".
